I was at CES yesterday and sat through the presentation by Panasonic. There technology works using those expensive "active" 3D display glasses. For those that don't know, basically they alternate flashing each eye an image on the screen.
They kept hyping up how awesome it would be to watch football in 3D, and showed use a 3D video of a football game. It was kinda neat, but anything that was moving fast (Such as arms/legs after the ball was snapped) turned into a flashing semitransparent mess. I'm assuming this is because they are alternative which eye is seeing the picture, and in the time it takes to switch eyes, fast moving objects have changed position.
And for systems that are smart enough to show images to both eyes at the same time, I'm curious how they will handle motion blur. That has always seemed to be a problem with 3D displays, as the eye wants to get the moving object in focus, however since the source is blurred they can't, which leads to eye strain.
